LOOM.

SPECIFICATION forming part of Letters Patent No. 628,228, dated July 4, 1899.

Application filed April l2, 1899. Serial No. 712,774. (No model.)

To all whom t may concern.-

Be it known tha-tI, JONAS NORTHROP, a subject of the Queen of Great Britain, residing at Hopedale, in the county of NVorcester and State of Massachusetts, have invented an Improvement in Automatic Looms, of which the following description, in connection with the accompanying drawings, is a specification,v

like letters and numerals on the drawings representing like parts.

This invention relates more particularly to that class of looms provided with automatic filling-supplying mechanism, whereby the,

Y the connections between the shuttle-feeler and the actuating means for the lling-supplying mechanism have been complicated, involving a number of parts.

My presentinvention has for its object the simplification and more direct. action of the means for preventing the transfer of filling when the shuttle is improperly positioned in the shuttle-box.

Figure 1 is a front elevation of a sufficient portion of a loom to be understood, provided with filling-supplying mechanism and having one embodiment of my invention applied thereto. Fig. 2 is a right-hand side elevation of the apparatus shown in Fig. 1, and Fig. 3 is a perspective view of the shuttle-feeler detached.

The loom-f rame A, the breast-beam A49, the

lay A3 having the bottom of one of its shuttleboxes cut away below the self-threadin g shuttle S, the filling-supplying mechanism, comprising connected rotatable plates suitably shaped to receive the ends of the filling-carriers b, (see Fig. 1,) the stud f, the transferrer f', mounted thereon and having the depending end f3 and a finger 2l, and the shaft d', adapted to be rotated by the movement of the weft-fork in the absence of the filling, are andmay be all substantially as shown in United States Patent No. 529,940, granted November 27, 1894, the parts hereinbefore referred to being operated in practice as hereinafter provided for.

The end f3 of the transferrer has mounted thereon a headed rocker-stud m, surrounded by a spring s, Fig. 1, one end of which is attached to the head of the stud and the other end to the part f3, the spring normally tending to turn the stud in the direction of the arrow 10, Fig. 2, said stud having secured thereto an arm m2, provided with a laterallyextended projection or lug m4, a notched dog mx being adj ustably secured to the arm m2 by set-screws 5 and 6, substantially as shown in United States Patent No. 568,455, dated September 29, 1896, said dog when moved into operative position being engaged by a bunter C2 on the lay when a change of filling is to be effected.

In order to prevent filling change if the shuttle is improperly positioned in the shuttle-box, the movement of the dog into operative position is controlled by a shuttle-feeler, and in my present invention the shuttle-feeler and the controlling con neet-ion between it and the dog is of a very simple character, as will be obvious from an inspection of the drawings, and more particularly Fig. 3 thereof.

The loom-frame is provided with a suitable bracket A10, on Ywhich is pivoted at a a yoke Y, Fig. 3, one of the upturned arms, as y, of the yoke being bent at its upper end to form a shuttle-feeler Q/X, the other arm y of the yoke being upturned and of sufficient length to directlyfengage the lug m4 on the dog-supporting arm m2. The yoke is provided with a lateral stud or projection 'Iz/2, on which is preferably mounted an antifriction roll g3, (see Fig. 3,) said roll being normally engaged by a detent-finger-d ,.ffast on the rock-shaft d and normally maintained in the position shown by a strong spring di, attached at its ends to the detent-finger and to the frame, respectively, as herein shown.

Referring to Fig. 2, it will be noticed that vwhen the shuttle-feeler and its rigidly-attached arm y' are in normal position the roll g3 will be between the fulcrum ct of the yoke and the lug m of the dog-support, and the spring CL3 being stronger than the springs the d og will he maintained in inoperative position so long as the detent-finger dx operatively en- IOO gages the yoke. Upon failure of the filling, however, the rock-shaft cl' is turned in the direction of the arrow 30, Fig. 2, as in the patent referred to, against the stress of the spring cl3, so that the detent-finger CZX releases the yoke and permits the shuttle-feeler to move toward the lay to detect the position of the shuttle, such detecting movement being effected in the present case by or through the action of the spring s, and if the shuttle is properly positioned in the shuttle-box the feeler is permitted to complete its full detecting movement, so that the controlling-arm y is moved sufficiently to permit the swinging of the dog mXinto position to be engaged by the. bunter C2 as the lay comes forward. Such engagement of the dog and bunter effects a change of filling. Should the shuttle be improperly positioned, however, it will be engaged by the feeler, so that the latter can complete its detecting movement, and the controlling-arm y' thus operates to prevent the movement of the dog into operative position.

From the foregoing it will be manifest that the connection between the shuttle-feeler and the actuating means for the filling-supplying mechanism is of the simplest character, and this will be especially obvious when the present construction is compared with that shown in Patent No. 568,455, referred to, or United States Patent No. 529,943, dated` November 27, 1894.

My invention is not restricted to the particular construction and arrangement of parts herein shown, as the same may be modified or rearranged without departing from the spirit and scope of my invention, for, so far as I am aware, it is broadly new to control the actuating meansv for filling supplying mechanism by a controlling member rigidly connected with the shuttle-feeler and in direct engagement with said actuating means.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom, the lay having ashuttle-box; filling supplying mechanism; actuating means therefor comprisinga spring-actuated dog and a bunter to cooperate therewith; a shuttle-feeler having a rigidly-connected arm in direct engagement with and to normally maintain the dog inoperative, and a detent for the feeler, operated upon failure of the filling to release the feeler and through the said arm to permit movement of the dog into operative position when the shuttle is properly positioned in the shuttle-box.

2. In a loom, the lay having a shuttle-box, a filling-transferrer, a pivotally-monnted dog operatively connected therewith; a spring to move it into operative position; and a bunter to cooperate with the dog; a shuttle-feeler having a rigidly-connected arm in direct engagementwith and to normally retain the dog inoperative against the action of the spring, and means actuated by failure of the filling to release the feeler and permit detecting movement thereof, and movement of the dog into operative position when the shuttle is properly positioned in the shuttle-box.

3. In a loom, the lay having a slotted shuttie-box; filling-supplying mechanism; actuatbunter; a shuttle-feeler provided with a rigid arm in direct engagement with and to control the position of the dog; means to move the dog into operative position and through the arm to effect detecting movement of the feeler, and means actuated by failure of the iilling to release the feeler.

4. In a loom, thelay; afilling-carriertrans ferrer having a depending end; a dog pivoted thereon; a bunter; a spring to move the dog into operative position; a shuttle-feeler having an upturned, rigidly-connected arm to directly engage and move the dog against the actuating-spring; and means to normally maintain the feeler and dog inoperative, said means being actuated upon failure of the filling to release the feeler.

5. In a loom, the lay; afilling-carriertransferrer having a depending end; a dog pivoted thereon and provided with a projection; a bunter; a spring to move the dog into operative position; a shuttle-feeler having an ing means therefor, including a dog and av integral controlling-arm'in engagement with `said projection,whereby movement'of the dog is controlled by the feeler; a stud carried by the feeler, and means, includinga detent-finger in engagement with said stud, actuated upon failure of the filling to release the shuttie-feeler.

6. In a loom provided with filling-supplying mechanism, actuating means therefor, a shuttle-feelerhavinga rigidly-attached member in direct engagement with and to control the operation of said means, and means actuated by failure of the filling to release the feeler and thereby permit the said actuating means to operate when the shuttle is prop erly positioned.

In testimony whereof I have signed my name to this specification in thc presence of two subscribing witnesses.
